You can devote yourself to Torah study, full-time or part-time, no matter what kind of Jew you are. Plenty of Modern Orthodox, Centrist Orthodox, “frum but not yeshivish,” and Chassidic Jews are serious about studying Torah.
In practice being Yeshivish means dressing in a certain way (black, usually velvet kippah, black hat, jacket while davening, white shirts), having a certain hashkafa (focused on the Yeshivish gedolim) which is not particularly mystical (kabbalah study is uncommon) but is certainly not rationalist, going to certain shuls and sending your kids to certain schools, and studying Torah in a certain way (focusing on Gemara and, maybe, halacha, while chassidim study chassidus too, or even focus on that, and more independent-minded people study whatever they want to study.)
It’s fairly common for Yeshivish women to work to support their husbands in full-time Torah learning for a few years (or even for their lifetime, though that’s less common outside of Israel), but it’s probably more common for men to work full time but study at a fixed time each day.
To me your hashkafa sounds most consistent with Modern or Centrist Orthodoxy. However, if you wear a black velvet kippah and/or other aspects of the Yeshivish uniform then at least some people will think of you as more yeshivish or at least “frum” between Modern and Yeshivish.
